BOBBIN.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed. December 23, 1907. Serial No. 407,634.

To all whom it may concern:

Be it known that I, \VILLIAM lV. BURKE, a citizen of the United States, residing at Bennington, in the county of Bennington and State of Vermont, have invented new and useful Improvements in Bobbins, of which the following is a specification.

This invention relates to improvements in bobbins, the object of the invention being to secure a bobbin which is provided with a device for holding a tag and connecting the same to the bobbin in such a manner that it will not interfere with the yarn as it is being fed onto or off of the bobbin.

The object of the invention is further to provide a device of the character set forth which shall be easily attached to bobbins now in use as well as to new bobbins, and which shall be cheap, durable and capable of bolding different tags, which tags may be quickly and securely attached by the device to the bobbin and easily detached therefrom.

The object of thus attaching a tag to the bobbin is first, to avoid confusing diiferent kinds of yarnthat is, the kind of yarn which is wound upon the bobbin is written upon the tag when the yarn is first wound on the bobbin, so that there is no possibility of confusing different kinds of yarn or different bobbins or of getting more than one kind of yarn on the same bobbin; and second, in case that any imperfect winding is done upon the bobbins, the operator who does such winding will be known by reason of the fact that the tag must bear his number, this being the rule, viz., that the operator shall place his number upon the tag of the bobbin upon which he winds the yarn. It will be understood that after the yarn is Wound on the large bobbin it is fed into a machine and made into cloth. If there are imperfections in the winding, such as longtailed knots, broken ends, waste ends, etc., there will, in consequence, be imperfections in the cloth, which, of course, means waste of material. Each operator or winder of yarn has a certain tag number and as the bobbins are wound he places his number upon the tag in the top of the bobbin wound by him, thus enabling the overseer to see at a glance who wound the bobbin. When a bobbin is found imperfectly wound, the attention of the operator or winder can be immediately called to it and the faults corrected.

The invention consists in a bobbin provided with a holder for a tag, the same being constructed as hereinafter described and particularly as set forth in the claims.

Referring to the drawings: Figure l is a front elevation of a bobbin with my improved holder attached thereto, showing a tag projecting from the top of the bobbin. Fig. 2 is a plan view of the upper portion of the same enlarged. Fig. 3 is a sectional elevation taken on line 33 of Fig. 2. Fig. 4t is a sectional elevation taken on line tet of Fig. 2. Fig. 5 is a sectional plan taken on line 55 of Fig. 3.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 6 is a bobbin of well known construction, the same illustrating the class of bobbins upon which yarn is wound from smaller bobbins. The top of the bobbin 6 provided with a cylindrical recess 7 into which is inserted the tag holder 8 which consists of a spring holder formed of a flat strip of metal bent between its ends to form a loop 9. The free ends 10, 10 of the strip of metal are brought together and form a clamp adapted to receive and hold a tag 12, said free ends terminating in outwardly extended ears 11, 11 at the extreme upper end of said holder.

The lower end of the holder is preferably V-shaped, as at 13, while the intermediate side portions 14, 14 extend outwardly from the opposite end portions of the holder and have frictional engagement with the inner walls of the recess 7 at points below said free ends. It will be noted that while the intermediate side portions let, let bear against the inner walls of the recess with sufficient frictional contact to firmly hold the holder in the recess 7 the upper ends 10, 10 of the holder being near together and, therefore, nearer the center of the recess 7, do not contact with the inner Walls of said recess, but are free to be spread apart sufliciently to receive the tag 12 therebetween. As a result of this construction the tag 12 can be inserted quickly between the free ends 10, 10, said free ends spreading apart to allow of such insertion, but when the tag is re moved the intermediate side portions 14, 14 cling firmly to the inner walls of the recess 7, so that said tag can be removed without displacing or withdrawing the holder from the recess.

In use, the knitter writes upon the tag the kind of yarn which is to be wound upon the bobbin. 'He also makes any further entries upon said tag which shall assist in the system in use in the particular shop in which he may be working.

Attention is called to the particular manner in which the spring holder is formed, especially in the following respects: The opposite sides 14, 14 of the holder bear against the interior of the recess 7 at points considerably below the upper or clamping end of said holder, and this renders it possible to have the holder fit closely in the recess 7 so that it will not be easily pulled out therefrom, as when withdrawing the tag from between the clamping ends of the holder, and yet renders it easy to insert the tag, for the very reason that the upper free ends can be moved apart without striking the walls of said recess. Moreover, the upper ends are bent outwardly at the extreme upper end of the holder, forming the prongs 11, 11 which constitute a means whereby the holder can be readily removed from the recess when desired without injuring the same or setting the points apart so .as to render them useless for clamping purposes.

It will be understood that my device is particularly intended for use in bobbins for yarn, such as are used in mills and in which the goods are knit for certain orders. Therefore, it very often happens that all of the yarn is not used which is upon the bobbin and may not be used for many weeks or even months after the first order has been filled therefrom. These yarns are used in various combinations to produce different results in the manufactured goods and hence in the practical business of the knitting mill a very large number of bobbins, extending into the thousands, are constantly in stock with a portion of the yarn left thereon. It naturally results that even if the ,knitter could tell with certainty the kind of yarn by its looks, he would be a long time finding .a certain yarn among so many bobbins, but

as a matter of fact large amounts of yarn were employed yearly in knitting mills to knit waste or rag stock, 1n order that the yarn might not be entirely lost, for the very reason that such yarn could not be picked out with certainty to fill certain orders. By using my improved device all of these bobbins can be set in rows on shelves, with the tags projecting from the holder and the number of the yarn thereon, so that the knitter can almost immediately pick out the bobbin containing the yarn which he dosires, by glancing along the row of bobbins and selecting the tag which has the proper number of yarns to fill his order written thereon. Thus the invention is extremely useful in saving time and money.

Having thus described my ,"l llVQHblOIl, what I claim and desire by Letters Patent to secure is:

1. As an article of manufacture, ,a bobbin provided in its upper end with a recess and a spring holder adapted to hold. a tag located in said recess, said holder consisting of a fiat strip of metal bent between its ends and the free ends brought together and adapted to clamp a tag inserted therebetween, said metal strip having frictional engagement with the walls of said recesses, at points below said free ends.

2. As an article of manufacture, :a bobbin provided in its upper end with arecess and a spring holder located in said recess, said holder consisting of .a flat strip of metal bentbetween its ends to form a loop, the free ends thereof brought together .and adapted to clamp a tag inserted .t herebetween, the intermediate portions of said loop extending outwardly from the opposite end portions thereof and having frictional engagement with the walls of said recess, at points below. said free ends. 7

3. As an article of manufacture, a bobbin provided in its upper end with a recess, a

spring holder located in said recess, said holder consisting of a strip of metal bent between its :ends to form a loop, the free ends thereof brought together and adapted to clamp a tag inserted therebetween, said free ends terminating in outwardly extended ears at the extreme upper end of said holder. 7

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
